Not sure why but ever since I flashed release 7 of the faux kernel my phone just seemed to get really warm, now I don't know if i just never noticed it but I'm running Motley kernel now and my phone just gets warm at the top when installing apps. I'm not sure if I never noticed it and I'm starting too or if I have a problem, HELP? Thanks.
That's completely normal. When installing asps the CPU is being used. Also, the CPU governor being used and uv'ing affect the temperature. Also, the CPU is located at the top I'm guessing.

Hey, I'm wondering too ! Since i flashed the latest faux kernel (release 007m) , my phone seems to be warmer than usual. According to the system tuner widget the phone runs around 45°C after a few minutes of use and sometimes reaches almost 60°C while i do nothing special on my phone (a little browsing, sms). Despite the fact that I've downclocked the cpu to 1.35ghz, put the governor on intellidemand, disable mpdecision, UV 75 mV and running at the stock gpu clock. I don't know if this is normal but this seems to be a lot. What's gonna happen if I play games or some more intensive apps?

How far have people got with over clocking their Visions?
Mines over clocked at 1GHz, i don't think id be increasing it any time soon think it would ruin my battery life
How far have all you all got to? Stable of course
That I know, we're at 1.8ghz so far. I keep mine at 806mhz all day since I barely use it throughout the day. Once I get home, I clock it up to 1.5ghz when I'm using it.
I've ran it once at 1.8ghz running a couple of benchmarks (linpack, neocore, quadrant)
It did very well, but, ran very hot (could be due to the fact I had it connected to the charger at the same time)
Either case, how much you get out of your battery depends on how you use it, how you set up your cpu profiles (dependant on which you use. I.e. cpu tuner, setcpu), and what frequency you're constantly letting your phone run on.
I run mine at 1.5ghz, see no need to push it further. Im getting all the performance I need at 1.5ghz. I use setcpu profiles, one to severely underclock when it reaches a certain temp and a charging profile that runs at stock clock to reduce heat when charging.
1.3ghz. Not like i feel it however. But 1.4ghz one they have posted wasnt 100% stable for me.
According to the System Tuner app, my CPU went up to 75 degrees Celsius while I was playing a track on Google Earth. I was running Earth for only a few minutes before it reached 75. I'm not sure if that's the peak yet...maybe it can go even higher.
I've seen several other threads about heat, but most people talk about 50s and 60s. Anyone reach 75C? The front and back of the phone, the top around the camera, were both very hot. It was almost uncomfortable to touch.
Again, I'm talking about 75 Celsius, not Fahrenheit. And I'm referring to CPU temperature according to System Tuner app, not battery temp. Anyone reach this?
picture plz.
the reason is bc someone did a stress test on the N4 and found that the device shuts down at ~57-59C (correct me if im wrong) to prevent damage to the hardware.
Edit: found the link http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
75ºC on a quad core?
I thought it was supposed to be more efficient than a dual core... 167ºF just seems like it's way hotter than any electronic device should ever be.

My first gaming laptop was an ASUS Republic of Game first generation. They did a horrible job cooling the machine. During the 2 months before the machine failed, the GPU would reaches 110 - 140 C if I played games (then, of course, the machine turned the GPU off and still ran as everything else was still about 70-80 C)
When the machine did fail, I opened it up, and found 2 fried thermal unit, a fried GPU and a nearly fried HDD) Amazingly, the machine stills runs, as long as I don't load GPU driver
Well, that's the story. Back to OP, as you see, if the temp is too high, you device can be literally fried. So if you turn off the thermal throttle, please enable it back on and do you best to keep your device cool
I tried to replicate just now and could only go up to 63c. I don't want to keep trying based on the comments here so far. If it happens again I'll be sure to get a screen shot and be aware of what's running.
Where would the thermal throttle toggle exist, if I have the capability at all? I'm running faux123 kernel and use trickster mod and trinity kernel tools for tweaking. I don't see anything about throttle control.
On a similar note, faux123 seems to default to 1ghz minimum cpu frequency. Does that seem right? I've flashed lots of kernels before on previous phones and they always default to the lowest value. When I force the setting down to 384mhz, it automatically changes back to 1024mhz the next time I go in my tool apps. Does this seem normal?

I haven't seen a Nexus 4 kernel that has thermal throttle toggle, or have it disabled yet. I am just checking if you're running one that I am not aware of

Minimum cpu frequency enforced by kernel is normal. I am not certain if faux123 default to 1 ghz min, but if it's the case, it seems weird for me too. Definitely not good for the battery. If there's no other CPU control apps, I recommend double check the settings, then find an update for faux123, or use trinity kernel
I just flashed a new kernel and my minimum cpu now seems more normal. I hopefully that alleviates the crazy temperatures too.
I'll try to test again tomorrow to see if my temps still go bonkers. It's time to sleep now. Thanks for the help, everyone.
I know that overheating in nexus 4 is common problem, but today after installing custom ROM CyanogenMod 10.1 my phone has started overheating more quickly. Is anybody know any solution of it?

overheating i doubt, what was the cpu and battery temperature? just because it feels warm, doesnt mean its overheated. when it actually overheats, first the cpu will lower in cpu speed(safety), then if that doesnt help itll shutdown. is the weather around you warm btw?

Also, if it's really getting to warm your phone would run unstable.

Thanks for your replay, I still don't understand why my mobile has started getting warmer more quickly ever since I've installed custom rom. I've hardly played any graphics intensive game on it so far.
I don't know from where to know cpu and battery temperature. Do I need to install any application from playstore? Weather around here is warm. On average 35-40 degree temperature.
My phone CPU reaches 70˚C and battery 50˚C when driving in my car, charing with gps on a this time of the year(hot as hell here as well).
Everything seems to be find, didn't even turn itself yet so I doubt theres anything to worry about.
My gf forgot her phone in the car stand in the sun for a few hours, when she came back it wouldn't turn on until it was cooler so you can be sure your phone can take care of itself.
Maybe your governor was changed when you flashed the ROM, depending on the governor (like performance) your cpu clock speed may be increased more often then with the original governor.
You can check your governor with apps like no-frills cpu or setcpu and check the temperatures with cpu z

its easier to use an app for battery and cpu temp. being 35-40C around you, id expect the phone to be warm most of the time. anyways, after installing a custom rom your device spends a lot of time syncing stuff. so itll be a little warmer than normal. after about a full battery cycle it should stop, and will be a little cooler. also, a reboot after several hours after a rom flash should help a little too.
Ok, thanks for your quick response.
I found when running Shadowrun Returns with the ElementalX 1.4 kernel http://forum.xda-developers.com/showthread.php?t=2389022 at 1.944 GHZ the back of the Nexus 7 gets hot. This worried me but I noticed when I installed the kernel was an option to use cool thermal throttling. I tried this and now the tablet does not heat up at all. You need to be rooted though to install the kerne of course not sure if ElementalX 1.4 works with stock though, I'm running the latest CM 10.2 nightly. It doesn't seem to affect the performance of either Shadowrun Returns or Wild Blood, the two games I'm playing at the moment, I still have the GPU overclocked to 487 and the Dalvik etc overclocked at the moderate ElementalX setting. . I think being able to run at 1.944 GHZ on my tablet with the cooler thermal throttling is better then running at stock and I believe that even some running at stock have that issue.
Hope this helps others that have this problem.

That's a good sign as you know the heat is being distributed effectively away from the internals. You don't need to be rooted to flash custom kernel. And setting different governors will have a major impact on your CPU.

You might be right about not needing to root to install a custom kernel though I couldn't find a definitive answer in the Nexus 7 2013 forums. I assumed it was needed from using custom kernels on other devices.
My device gets hot while gaming. When you are doing intense gaming like I am I'm sure pretty much any governor will max out the CPU. I know Intellidemand which I use does for sure.
When overclocking, heat is the enemy and it can damage, crash CPUs and even affect the performance of them. I believe if you are concerned about your Nexus 7 heating up (mine does for a good area between the logo and the camera when not using the ElementalX cool thermal throttling) then my advice is good.
Peace.
P.S. How the heck have you done 675 posts since June 2013?

Kernel is flashed separately from the ROM. Rooting is only for running apps like Trickster Mod to configure to kernel. Otherwise you can have stock 4.3 ROM with any kernel you want. Heating up will obvious affect performance due to thermal throttling but I was not concerned of damage even when the CPU of my 2012 Nexus 7 got to 80 degrees celsius from running overclocked performance stress test under direct sunlight in a case. If your CPU crashes then it's likely not overclocked correctly. Otherwise if it remains stable under artificial stress test, it will handle any game no problem.
I would really appreciate if someone explain me how exactly this function works?
I mean, tablet don't have fan, so how it keeps the cpu cool, and also what this option does to my nexus in order to keep it cooler?
I would not over clock this device. It us more than fast enough for any Android game.
Throttling does just what the word describes. In basic terms your cpu will be slowed down when getting hot and this defeats the purpose of over clocking.
I won't mention the instability that can be caused or the possibility of doing damage.
Just my thoughts.. To each how own and I do have my I7 pc cpu over clocked big time but it has a huge fan.

I agreed, throttling and over clock doesn't make sense but this CPU is underclocked and it is designed to go higher like the one on the galaxy s4 and the GPU is meant to go higher but due to battery life Google underclock it

Well , its not under clocked by Google, this is underclocked cheap from the factory , its just a lower bin s600 that has been rebranded as S4 Pro .. If it was regular s600 it wouldn't be underclocked .

When the CPU reaches a certain temperature threshold it begins to cycle down the CPU speed in order to cool down the processor. It makes the CPU start running at lower frequencies to keep it cool.
Exactly, so a quick oc and u got a better processor without worries of damaging the chip

Trickster Mod Thermal Throttling Settings
Hey,
If your CPU is getting hot (especially if it's overclocked and hitting 80 C or near to it) At 1944 the back of my case would get noticeably hot. I still say it isn't good for the CPU. From what I know about overclocking if any CPU gets too hot it can damage the CPU or degrade it over time. I definitely wouldn't want it even getting to 80C before it throttles but I found in Trickster Mod, even the free version, you can set the throttling to custom settings if you are rooted. Custom kernels set their voltages to scale depending on the clock speed which means lower clock speeds, less voltages, less heat. I'd rather keep the temps lower on the CPU then risk damaging the device or degrading it over time. Also you can undervolt the CPU at the kernel different clock speeds so it heats up less. You can run the free AnTuTu Benchmark stability test to see if your clock speed voltages are stable and will not crash your device. I have my CPU overclocked to 1944, thermal throttling down clocks the CPU to 1836 at 73 C, 1620 at 75 C, 1512 at 77 C and 1134 at 80 C. My voltages I lowered and are stable at 1944 - 1087500, 1890 - 1062500, 1836 - 1035000, 1728 - 1025000, 1620 - 1000000, 1512 - 987500. The lower voltages are undervolted as well but not going to list them all here.
Peace,
KedarWolf
P.S. When it was posted in this thread you can install custom kernels without rooting it is correct, I recall reading that at one point. Like it was said to use Trickster Mod, change governors or custom throttling settings you need to be rooted.
Bump bump
Phone: VS995 Rooted running WETA rom + Werewolf Kernel.
Issue: Phone heavy CPU throttling when charging, gaming or even just booting. The CPU throttles to 652mhz on the small cluster and 1036mhz on the big cluster whenever I do something cpu intensive for a couple minutes. Obviously this causes a lot of stuttering and lag. I have to let it sit untouched and it will go back to normal.
I've monitored the temps and CPU doesn't go above 50c when playing games and my battery temp is below 25c. Even if the cpu temps go back down to 35c, it takes a while for the frequencies to ramp back up to max.
I'm using EX kernal manager and have disabled core_control and msm_thermal but doesn't help.
I've tried the stock WETA kernel and Werewolf kernel but they both don't seem to affect the heavy throttling at all.
Wondering if there is a kernel or a fix for this, kinda like the lg g3 thermal mitigation setting, or the CTTMOD found on other devices? Or maybe my device needs to replace thermal paste?
Thanks!

I've noticed this as well on WETA but only when charging. For some reason on WETA on stock kernel this phone slows down dramatically when plugged in. I just thought it was LGs method of thermal control but on MEGAROM V4 it doesn't slow down at all for me when plugged in so idk but would like to know how to fix cause I have it plugged in during driving a lot and switching back and forth between music and navigation becomes frustrating because of how laggy it gets

Yes! That's exactly what I'm experiencing too.
Having it plugged in throttles the cpu immediately. Doesn't matter if it's a quick charger or a slow charger. The battery and CPU temps are both low so that's not an issue. Even when it reaches 100% battery and just trickle charging, it still throttles randomly.
I'll start a different rom and see if it helps.

Having the same issue
My phone always stay Cool even when charging but cpu frequencies keep changing.
Even when i set the cpu max to 2105mhz it automatically slow down to 1036mhz , which makes the device super laggy and shuttering.
I've tried stock rom,weta,and some other roms and also tried some kernels nothing seems to be fixing the issue but Resurrection remix rom fixed it, no frequencies changing no lag no shuttering but i also has a problem that second screen doesn't work at all :/
yep same issues stock here.. just made a topic and realized you made this lol. stock rooted fwiw. I can't stand it. this phone has become such a lag fest that the galaxy s6 I was given for work seems faster, and that's two years old.
